A10.0-kg animal is running at a rate of 3.0 m/s. what is the kinetic energy of the animal?

hint: 1/2 (m)(v)2
• 3.3 j
• 45.0 j

Kinetic energy is calculated by using formula:

Ek = 1/2*m*v^2

Now we replace values of mass and speed in this formula.

Ek = 1/2*10*3^2 = 45.0J

When you have a formula and all variable values are given in the text of question just replace variable values in equation and find the final value.

B) as the temperature increases, the kinetic energy of the particles increases.|-/
